astings requiring the making lof a substantial number of individual'castings subsequently assembled by bolts, nuts, Vrivets and the like to form the Ventilating thimble, in which the exposed portion ofthe Ventilating thimble ;A

`viewed from the room or other place where it is positioned has an exposed flange and ears through which anchoring screws or bolts are positioned in order to mount the ventilator in l position on awall over the chimney opening so it will support a stove pipe. This sort of construction has'presented many diiiiculties both in the making of the parts, the assembly of the parts andthe mounting of the ventilating thimble on the wall which requires an 20Y unusual amount of timeand labor in order to properly place the support for the stove pipe and the ventilating thimble in position over the chimney opening in the wall. lt is customary in most instances to make the openlng communicating with a chimney through a I wall much larger than the pipe from the stove which is to enter the chimney and in making a device of this character provision must be made for covering up the unsightly appearance resulting` from the difference in size be-` tween the opening in thewall and the stove pipe. A K i y The present invention overcomes substantially all of the disadvantages of these prior constructions and provides a simple and ef ficient construction which may be placed in position without the use of any securing screws or bolts or other similar means in the opening in a wall communicating Ywith a chimney, which will provide a means for receiving a stove pipe of smaller diameter than the opening in the wall and at the same time provide a spacing plate to cover the opening between the pipe and thewall which also takes advantage of this opening to secure ventilation of the room with which itcommunicates so as to make a neat finish on the wall adjacent parts are rigidly connected together including a sleeve member adapted to fit the standard size of opening usually placedin the wall i communicating with the chimney which will support the Ventilating thimble of this inven-r tion by insertion of the sleeve into the opening, a ring secured tov the sleeve and seating against the wall around the opening and a facing member being provided for concealing all of the other parts ofithe invention from view and providing a neat appearing structure against thewall around the opening-which is provided with an opening to receive the stove pipe and center it in the Y opening in the wall communicating with'the chimney and which is also provided withV openings adapted to permit the draft in the chimney to withdraw the air from the room and thereby provide ventilation in the room. The specificconstruction of the invention and other features of novelty are more particularly pointed out in' the following detailed description and in the claims directed tothe preferred form of construction, it being understood, however, that various changes may be made in the'speciiic relation between the parts without departing from the spirit or the scope of the invention as herein described and claimed. 4

In the drawing forming cation, n

Fig. l is a perspective view showing the invention applied in the chimney opening in a wall and showing a stove pipe extending through the facing member thereof for communication with the chimney. y

Fig. 2 is a central longitudinal Vsection through the improved stove pipe Ventilating thimble showing portions in elevation.

The improved stove pipe ventilatingthiml ble comprising the invention is formed entirely of sheet'metal and inclu-des a sheet.

the usual manner well known in the art so that the sleeve will readily enter an-d slidably engage in the opening ina wall communicating with a chimney. The opposite end of this sleeve l is provided with an inwardly eXtendingfold portion 3 fterminating in an outf,

part of this appli- Awardly extending fold portion 4 spaced slightly from the portion 3 to provide an outwardly facing annular channel which receives` the inn-er edge of the sheet metal ring The portions 3 and 4 are firmly engaged with the inner edge of the ring 5 about which they are formed in assembling the sleeve and, the ring. This ring 5 extends radially outwith theouter edge of the ring. The facing Y member is otherwise spaced from the ring and sleeve as `illustrated in Figure 2 and is formed with a central opening 9 of smaller diameter than the sleeve 1 and of a size to slidably receive the usual standard size vof stove pipe used with gas ranges and other types of cooking and heating stoves for houses and apartments. The inner edge of the facing member 6 adjacent the opening 9 is provided with a rounded section indicated at 10 terminating in an inwardly or rearwardly directed cylindrical portion 11 which extends towards the sleeve 1 and forms a pipe supporting portion.l The rounded portion l0 facilitatesthe insertion of a stove pipe 12, as shown in Figure 1 in full lines, and in dot-ted lines in Figure 2, into .the opening 9 for sliding movement through the portion 11 so that the end of the pipe 12 will terminate adjacent to the free end of the sleeve 1, for example, as illustrated in Figure 2 in dotted lines.

The facing member is formed around the central opening 9 and in spaced relation thereto with a plurality of smallopenings 13 which forni Ventilating openings. Y

By the above described construction a stove pipe Ventilating thimble is provided which is formed of three parts rigidly assembled together in the mannervdescribed and illustrated which may be readily applied in the opening in a wall vof a dwelling or other building provided for a stove pipe, the sleeve having the free Vend inserte-d in this opening which it is constructed to slidably fit. This sleeve is entirely inserted into the opening so that the ring 5 engages the face of the wall adjacent the opening as a result,

of which the facing member 6 is .the only part exposed to view after this stove pipe support; and Ventilating thimble is applied inthe opening in the wall.v Then the stove pipe is inserted through the opening 9, the rounded portion 10 facilitating the engagement -of the vend inthe opening, so that the end will extend intoY the sleevev 1 andV terminatecin Va position adjacent the part where the opening inthe wall communicates with the chimney as a result of which the draft in the chimney will draw the fumes'a-nd vapors from the stovepipe into and up the chimney for discharge in the usual manner. This stove pipe will be spaced from the sleevey 1 thereby providing an annular passage around the pipe into the chimney with which the openings 13 communicate so that the draft in the chimney will also create a suction in this annular space, to draw theA air in the room through the openings l13 and up the chimney, thereby Ventilating the room at all times. This Ventilating thimble is of particular value to housewives for yuse in the kitchen whether gas ranges, electric ranges or other stoves are used in order to Ventilate vthe kitchen ,and withdraw the vapors and fumesA from cooking' continuously so that they are not distributed 'in other parts of the dwelling. By making the parts of sheet metal together with the special manner of assembly as above described provides a simple and easily manufactured pipe support and Ventilating thimble'which may be made and sold at a very reasonable price and which does not require any special labor, bolts, nuts, screws, tools or. any other parts to support the device, and which requires nothing but the slidable insertion of the sleeve l into thev Y provide fold portions engaging the opposite sides `of the inner edge'of said ringv and rigidly connecting said sleeve and ring, and a sheet metal facing member of frusto-conical form having its outer edge formed to provide an inwardly facing channel receiving the .Outer edge of said ring and rigidly connecting said ring and facing member, said facingmember having a central opening and having the marginal portion adjacent said opening formed vto provide a curved section terminating in a cylindrical pipeY supporting portion extending toward said sleeve and of smaller diameter than said sleeve, said curved section being adapted to guide a pipe into said pipe supporting portion, and said facing-member having a plurality of Ventilating openings formed be-Y tween the inner and outer edges thereof.

2.*A stovepipe Ventilating thimble com prising a sheet metal sleeve, a sheet metal ring, one end of said sleeve being formed to provide fold portions engaging the opposite sides ofthe inner edge of said ring and rigidly connecting said sleeve and ring, and a sheet metal facing member having its outer edge formed to provide an inwardly facing channel receiving the outer edge of said ring and rigidly connecting said ring and facing member, the remaining portions of said facing member being spaced Jfrom said ring and having a central pipe receiving openingv and p a plurality of small spaced openings formed therein, said pipe receiving opening having a smaller diameter than said sleeve and bev ing substantially in axial alignment therewith.

3. A stove pipe Ventilating thimble comprising a sheet metal sleeve, a Sheet metal ring having its inner edge rigidly connected to one end of said sleeve, and a sheet metal facing member having its outer edge rigidly attached to the outer edge of said ring and the remaining portions spaced from said ring, said facing member having a. laterally eX- tending iange deiining a central opening of v'smaller diameter than said sleeve and aligned therewith, and having ventilating openings therein spaced around said central opening. i
